The best way to charge a battery is using a 4 step battery charging curve, which cannot be achieved from a standard alternator. A standard alternator cannot output a large enough charge to power an auxiliary battery bank.

The Digital Mobile Charge provides your extra battery system a charge that is approximately 5 times faster than could be achieved in using the vehicles alternator. This provides in-transit charging of extra battery banks and increases the life of the batteries by de-sulphating them.

Digital Mobile Charging provides the same utility as an advanced regulator, a zero loss battery isolator, and a 4 step battery charger!
